To all whom it may concern.' Y

Be it known that I, FREDERICK A.. Seriossow, citizen of the United States, residing at Detroit, county of WTayne, State of Michigan, have invented a certain new and useful Improvement in Flushing-Valves, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to4 which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to flushing valves shown in the accompanying drawingsl and more particularly pointed out in the following specification and claims.

Une object of the invention lis to provide a `simple and effective device in which the usual rubber ball valve is eliminated.

Another object 'of the invention is to provide a construction whereby thev valve is held to its seat through the action of a float until manually raised, whereupon the float serves to maintain the valve off itsseat, un-

til the altitude of the water in the tank isV tional view through the device, showing a fragment of a flushing tank, with the flushing valve seated.

Fig. 2 is a similar view showing the iiush-` ing valve raised, and the inlet valve or ball cock open.

Fig. 3 is a detail viewpof the operating lever, with parts in section.

Fig. 4 is a plan lview of the liushing valve and operating mechanism.

Fig. 5 is a detail view-partly in sectionof the rocker arm with which the ball float and flush valve are connected.

Referring now to the letters of reference placed upon the drawings A, denotes the ushing tank. B, the inlet valve or ball cock. C, indicates the iiushing valve proper. D, is the casing 0f the flushing valve and D is its seat. C, is a valve stem for guiding the valve to its seat. F, denotes an overflow pipe opening into the casing of the valve D through a hole projection D2 extending laterally from the valve casing, said laterally directed hole projection D2 having a portion D3 extending into the valve casing D and provided with anaperture D4 through which the stem C operates to guide the valve C to its seat D.

G, is a bracket secured to the upper end of the overflow pipe in which isjournaled a rock shaft H. l, denotes a link connecting one arm of the rock shaftv with the manually operated lever J, supported in the wall of' the flushing tank. K, indicates a link connection between the flush valve C, and another arm ofthe'rock'shaft H. L, is a ball float provided lwith an adjustable rod M, pivoted to still another arm of the rock shaftmH. N, indicates an adjustable screw for regulating the tilting action of the rock shaft H. O, is a turn buckle for adjusting the lenffth of the rod M. P, is a guide 'for the rod ,supported upon the overiiow pipe.

Having indicated the several parts by reference letters, the construction and operation of the device will be readily understood.

When the liushing valve C, is seated and the tank is full of water, as indicated in Fig. l of the drawings, the upward thrust of the ball float L,-due to its buoyancy-will through the rod M, acting upon the rock shaft H, and the link connection with the flush valve, serve to maintain the latter upon its seat until manually raised through the operation of the lever J.

The lever J, having been operated, the fiush valve is thereby lifted from its seat due to the link connection between it and the rock shaft H. The rocking shaft H, having now assumed the position indicated in Fig. 2 of the drawings, the upward thrust of the ball float-due to its buoyancy-acting upon the rock shaft, will maintain the flush valve in its raised position until the level of water in the tank has been reduced to a point where the buoyancy of the float is no longer effective to support the valve, whereupon it will Adrop to its seat by gravity, thereby permitting the tank to again fill with water. By adjusting the screw N, the rocking action of the shaft connection between a third arm of the rock 2. In a device ofA the `class H may be controlled, that it may always be in Iposition for effective operation.

aving thus described my invention, what Iclaimis:-V p -1. In a device of the character described, a tank, a flushing valve, an overa-How pipe, a'bracket secured to the upper end of the over-flow pipe and projecting. 'laterally therefrom, a rock shaft mounted inthe outer v end ofV the bracket and thereby spaced from the over-iiow pipe and provided with arms, an` operating lever, a link between the operating lever and one of the arms of the rock shaft, a iloat member connected to another of vthearmsfof the rockshaft, and a link shaft andV said valve. l

described, a tank, a iushi'ng valve, an over-flow pipe arranged vertically in the tank and having communication with the flushing valve, a bracket secured to the upper end of the overflow pipe andlprojecting horizontally therefrom, a rock shaft'mounted in the outer V end of theV bracket and provided with arms, an `operating lever, a connection between the operating lever and the rock shaft, a

' ioat member in the tank having connectlon with an arm'of the rock shaft, and a link connection betweenI another armoof thefrock` shaft and said valve.Y Y 3. In a device'of the character described,

Y a tank, a flushing Avalve in the tank, anoveriow pipe in the tank, a bracket secured to theY over-flow pipe, a rock shaft mounted Y lated arms, a ilush valve suspended from one of the arms of the rock shaft, means for guiding the flushing valve to itsl seat, afioat having a suspension rod connected with the other of said arms of the rock shaft, a guide eye for the float rodfthe arm ofY the rock' shaft connected with the float being movable to aposition at one side of the line joiningthe pivotV and ioat for. forming valockv to hold the oat against upward movement and the valve on its seat, andfmovable to another position at the opposite side of the said line-to release the loatand permit the same to support the valve in an vopen position whilethe entire iiushing water is being discharged from the tank, and manually operable means for operating the rock shaft. In testimony whereof I sign this specification inthe presence of two witnesses.
